A spirit level for the installation of tile and cabinets includes a rigid body having upper and lower parallel planar surfaces separated by a first predetermined width. The body includes a bubble vial oriented to verify the horizontal orientation of the level. An auxiliary edge portion has a planar top surface and a planar bottom surface parallel to the top surface separated by a second predetermined width. Means, such as a tongue and groove or hole and pin arrangement are provided for removably attaching the auxiliary edge portion to the upper planar surface of the rigid body, thereby providing a level having two standard widths corresponding to industry standard tiles. A series of evenly spaced holes are provided for removably securing the rigid body to a flat surface. An additional bubble vial is fixedly attached to the rigid body for indicating when the upper and lower planar surfaces are vertically oriented. The first and second ends of the rigid body include parallel planar end surfaces normal to the upper and lower planar surfaces. A series of frictional pads are fixedly attached to the back surface of the body and serve to facilitate positioning the level on the flat surface.
